Question: Including Band Math data in l2bin

Re: Including Band Math data in l2bin

Currently, l2bin takes an L2 file or NetCDF4 file with similar format as ifile. I was able to use gpt to write the output of bandmaths to a NetCDF4 file, but l2bin is not able to get the necessary information from the file.

Re: Issue with mosaicking Landsat images

Please provide one example with the filename of your Landsat L2 images on which you did mosaic and got questionable results

Question: Trouble to run measured remote sensing reflectance as seabass (.sb) to run l2gen

Re: Trouble to run measured remote sensing reflectance as seabass (.sb) to run l2gen

l2gen takes a Level 1 file as ifile. It does not take seabass file as input file. See https://seadas.gsfc.nasa.gov/help-8.4.0/processors/ProcessL2gen.html#COMMAND_LINE_HELP For SGLI mission, your ifile would look like something like this -- GC1SG1_201811110139G05509_1BSG_VNRDL_0176.h5 or GC1SG1_2018...

Re: Unable to view contents of L3 DAY CyAN NetCDFs

SeaDAS does not provide a reader for L3b files. You can use l3mapgen to create L3m files from L3b, which SeaDAS can read -- https://seadas.gsfc.nasa.gov/help-8.4.0/processors/ProcessL3mapgen.html

Re: OCSSW satellite validation matchup tools: val_extract failed

Thanks, Anna for sharing the content of matchup_entries.sb. I did replicate the error. It seems val_extract got called, but returned with error, and the error message was not helpful.

We are investigating the issue.

BTW, can you do seadas_info and share the result here?

OB.DAAC provides L3 mapped files with 4km and 9km resolution, but you can make your own L3 mapped files with higher resolution using SeaDAS -- https://seadas.gsfc.nasa.gov/ 1. download L2 files with the desired time and area from OB.DAAC -- https://oceancolor.gsfc.nasa.gov/cgi/browse.pl?sen=amod 2. ...

Re: OCSSW satellite validation matchup tools: val_extract failed

I can download AQUA_MODIS.20110520T132501.L2.OC.nc from our site. If your seabass file is downloadable, you can share the link so I can download the file. Otherwise, you can replace the filename matchup_entries.sb with matchup_entries.txt, and share the file here.

Re: Cloud cover or similar data - Modis Aqua

I noticed that you are still using SeaDAS 7.5.3. Maybe you could try 8.4.1, which has almost all the features of 7.5.3, plus a lot more?
